Improvement in harvesters



UNITED STATES PATENT OEETEE,

JAMES PINE, OF TROY, NEV YORK, ASSIGNOR TO HIMSELF AND J. J. VIELE, OFSAME PLACE.

HVIPROVEIVI ENT IN HARVESTERS.

Specification forming part of Letters Patent No. 33,557, dated October22, 1831.

.To all whom t may concern,.-

Beit known that I, JAMES PINE, of Troy, in the county of Rensselaer andState of New York, have invented certain new and useful Improvements inGrain and Grass Harvesters; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the annexed drawings, making a part of this specification, in Which-Figure 1 is a side sectional view of my invention, taken in the line xx, Fig. 2; Fig. 2, a front sectional view of same, taken in the line yy, Fig. 1.

Similar letters of reference indicate corresponding parts in the twofigures.

This invention consists, first, in an improved manner of hanging thegear frame, second, in an improved arrangement of devices for securingthe finger-bar against horizontal deflection and insuring its freedom ofmotion in a vertical plane.

To enable those skilled in the art to fully understand andconstruct myinvention, I will proceed to describe it.

A represents an axle, on the ends of which wheels B B are placed, and Cis the main frame of the machine, through which the axle A passes.

D is the draftpole, which is attached to the front end of the main frameC by a horizontal bolt or pivot, a, said bolt or pivot passing through asocket, l, in which the draft-pole is tted, the socket being firmlysecured to the main frame.

On the axle a there is fitted loosely a band, c, to which a bar, d, isconnected, said barbeing perforated and fitted in a slot in the back endof the draft-pole D.

Through the back end of the 'draft-pole a pin, e, passes horizontally,said pin passing through either ofthe perforations of the bar d. Byadjusting the pin e higher or lower in bar d the main frame C may bemore or less inclined, and the iingenbar and the front or cutting edgeof the sickle, hereinafter referred to, brought nearer to or fartherfrom the surface of the ground, as may be desired.

At the back part of the main frame Cthere is placed a shaft, E, on whichthe back part of a gear-frame, F, is tted loosely and allowed to swingfreely.

On the shaft E there is fitted loosely a wheel, G, which wheel has apinion, H, attached concentric( lly to it, said pinion gearing ormeshing into teeth at the inner side of wheel B. The gear-frame F may beof V forni, its forked or branched back end being fitted on the shaft E,and its front end having the finger-bar H attached to it by a joint, f.On the finger-bar a sickle is placed and driven from the wheel G by anyproper means. The finger-bar H is braced by a rod, I, from shaft E.

To the right-hand side of the main frame C there is attached a lever, J,which lever has a pulley, K, secured to it.

To the lever J there is also attached a ratchetsegment, L, with which ap'awl, M, engages. This pawl M is provided with a foot-piece, g, whichprojects from it at the point where its fulcrum-pin h passes through it.

On the pin h there is placed a half-pull ey, N, to the periphery ofwhich a chain or cord, i, is attached, said chain or cord passing downand being attached to the finger-bar II. The chain or cord lalso passesaround the pulley K, and is brought forward and attached to thefoot-piece g of the pawl M. By this arrangement of the half-pulley N,pulley K, and chain or cord fi, the finger-bar and sickle may be veryreadily elevated, not much power being required to effect the result.The pawl M, by engaging with the ratchet-seg1nent L, retains thefinger-bar at the desired height, and the pawl may be disengaged fromthe ratchet-segment at any time by depressing the foot-pieceg.

By attaching the gear-frame F to the main frame C, as described, andhaving the wheel G placed loosely on shaft E, and not connected directlywith the gear-frame, the latter will not have any downward pressureexerted upon it, as would be the case were the wheel G connected withit. This is an important feature of the invention, for much friction isavoided by the pressing down ofthe finger-bar on the surface of theground.

By having the draft pole D arranged as shown, so that its back maybeadjusted higher or lower, the sickle may be made 'to out higher orlower, as desired, and by having the fingerbar H attached to the frontend of the gearframe F by a joint, f, and the back end of the gear-framefitted loosely on shaft E, the iinger-bar is allowed to conformperfectly to the inequalities ofthe surface of the ground, While 2. Thecombination of the finger-bar H. the rod I serves as an ecient brace forthe joint f,gearframe F, Xed shaft E, brace-rod iinger-bar. I, axle A,and main frame C, constructed, ar-

Having thus described my invention, what I ranged, and operating in themanner and for claim as new, and desire to secure by Letters thepurposes herein shown and explained. Patent, is- 4 T l. The combinationof the gear-frame F and JAMES PIB D gear-Wheel G II, j ournaledindependently upon a shaft, E, secured rigidly in the main frame C inthe rear ofthe axle A. y
